Figure 1
Figure 1. Normal right kidney in longitudinal view. Arrow: cortex, star: hypoechoic medullary pyramid, dot: renal sinus with hyperechoic fat. Video S1 can be found in supplementary material.
Figure 2
Figure 2. Hyperechoic kidney seen in a patient with chronic kidney disease. Note that the kidney echogenicity is described relative to the liver parenchyma. Video S2 can be found in supplementary material.
Figure 3
Figure 3. Moderate hydronephrosis with the classic bear claw appearance caused by dilation of the major and minor calyces. Video S3 can be found in supplementary material.
Figure 4
Figure 4. Severe hydronephrosis with ballooning of the calyces and effacement of the renal cortex (yellow arrow). Video S4 can be found in supplementary material.
Figure 5
Figure 5. A) The width of the bladder is measured in the transverse view. In this image, the width is approximately 10.5 cm. Also seen in this image is a dilated left ureter as it enters the bladder at the UVJ (yellow arrow). Video S5a can be found in supplementary material. B) The depth (double ended yellow arrow) and height (double ended white arrow) of the bladder is measured in the longitudinal view. In this image, the depth is approximately 4.2 cm and the height is 11.7 cm. Using the width measurement in the above figure, this patient’s estimated bladder volume is 10.5 cm x 4.2 cm x 11.7 cm x 0.52 = 268 mL. Video S5b can be found in supplementary material.

Figure 6. A) 1.8 cm stone in the UVJ (yellow arrow), seen in transverse. Video S5a can be found in supplementary material. B) Stone in the UVJ (yellow arrow), seen in longitudinal and measuring approximately 1.6 cm. Note that the ureter is severely dilated. Video S5b can be found in supplementary material.
